The Book of Knowledge
The Children's Encyclopedia
Every teacher knows the marked difference
between the child who reads for informa
tion and the one who does not. That
difference continues all through life. The
Book of Knowledge makes reading children,
observant children, children who succeed
easily in what they attempt.
THE great departments of The Book of
Knowledge tell the child or youth what is
most worth knowing and they are fasci
natingly illustrated by nearly everything worth
seeing. The Book of Knowledge forms a mar
velously handy little library of nature, science,
history, biography, art, literature and manual
activities. It is a delightful source of read
ing, entertainment, instruction and reference
during the entire period of school life.
Now in the Homes of
Almost 3,000,000 Children
The Book of Knowledge is in the hands of close upon
three million children today, and has been printed in
six different languages. It is never off the press. It
has become the children's friend and helper in all the
major activities of their daily lives, and their most
important help in getting an education that will
satisfy the demands of the challenging life of today.
Pictures are the most effective means of conveying
quickly a fact, an idea, a process, a story. The Book
of Knowledge shows 15,000 striking educational pic
tures, 3,400 in beautiful color and gravure. Here is
visual education in its simplest, finest form.
Makes Reading Children
The arrangement of The Book of Knowledge is one
of its most successful features. It is based on the
natural working of the mind of a child-from the
Known to the Unknown-from the simple to the more
complex-and never too much or too heavy mental
food at one time. The articles are of exactly the
right length to hold and not weary the attention.
